With all the progress being made in the energy industry, I don’t think there’ll be any new gasoline / diesel vehicles manufactured from 2030 onwards. This applies to aircraft and heavy earth moving equipment as well.

Honda FCV

The 1^st commercially available hydrogen Fuel Cell (FC) car was the Toyota Mirai. Unfortunately it was a 4 seater sedan, so right out of the gate it was never going to be a very practical car for most people. Both the Mirai & the new Honda Clarity FCV claim a hydrogen tank capacity of 5 kg, which should be enough for cruising range of around 500 miles (800 km) if we assume an FC Efficiency of 60%. However, their EPA rating stands at 300 miles, so that means an actual efficiency of just 40%. Present day PEM FC technology, which is what’s being used for these vehicles, allows for as much as 70% efficiency, but obviously the car makers just haven’t gotten there yet. Other FC designs, such as Solid Oxide FC (SOFC) can go up to 85% efficiency in Combined Heat & Power (CHP) systems.

The Hyundai iX35 FCV is another fuel cell vehicle on the market today. It has a 5.6 kg hydrogen tank and can only do about 369 miles. The one advantage both it and the Honda Clarity have over the Mirai is they seat 5 people. See below a comparison of all the 3 vehicles.

Fuel Cells will in the future also be added to bicycles as well. They’ll work a lot better than the present day battery systems currently in use. UPDATE: Just discovered the below Fuel Cell bike from Linde. This is a prototype released in October 2015. It supports assisted pedaling over a range in excess of 100 kilometers (63 miles) from only 34 grams of hydrogen and can be refueled in 5 minutes.
